Can I port FTM from one PC to another?

Can I port FTM from one PC to another?

I did not see this covered in FAQ. I have FTM and a lot of media on a 64-bit Vista machine. I just got a 64-bit Windows 7 Pro machine, which will connect with any machine on my home network as long as it is also Windows 7.

Do I need to buy another copy of FTM or can I download under the same license?

Presuming I cannot transfer files over the network, would appreciate suggestions for porting the FTM directory.
